Pregnant women eat fish baby smarter

Researchers recently found that the more pregnant women eat fish, the more likely they are to have full term pregnancy, and that babies born at birth will be healthier and more mental than normal babies.

Researchers at the Standus-Selum Institute in Copenhagen compared the diet of 8,000 pregnant women, asked how often they ate fish during pregnancy, and whether the fish they eat were cooked hot food or in salads. Eat cold food or fish oil supplements. The results showed that those pregnant women who frequently eat fish have a higher probability of producing premature babies and giving birth to a lower-weight baby than those pregnant women who do not normally eat fish or rarely eat fish. The survey also found that eating fish once a week can reduce the likelihood of premature delivery of pregnant women who never eat fish from 7.1% to 1.9%.

The researchers concluded that the reason why fish is good for pregnant women is because it is rich in omega-3 fatty acids. This substance has the effect of prolonging pregnancy and preventing premature delivery, and it can also effectively increase the weight of babies at birth.

This study by Danish scholars and similar previous studies have reached a similar conclusion, that food fish can improve the possibility of full term pregnancy. In fact, fat-rich fish such as salmon, mackerel, and tuna are not only beneficial for pregnant women, but also treat depression and inhibit the growth of prostate cancer cells.

The results of this study by Danish scholars will be published in the latest issue of the British Medical Journal.

Finding: how smart pregnant women eat fish

● Fish is rich in amino acids, lecithin, potassium, calcium, zinc and other trace elements, which are essential for fetal development, especially the nervous system. Investigations and studies have shown that pregnant women eat more fish to facilitate the development of the fetus, especially the brain's nervous system, so that the baby born is particularly smart. However, the problem of environmental pollution has become increasingly serious. Mothers are worried that the pollution of fish will not cause some negative effects on the development of the fetus. The investigators specifically investigated mothers and young children who had eaten mercury-containing fish during pregnancy. To understand the impact of heavy metal mercury pollution on the intellectual development of young children, the researchers conducted research on six neural development indicators.

● Research data shows that the mercury content of the local people is 10-20 times higher than the average. However, there is no significant negative impact on children’s cognitive, language, reading, mathematics, vision, and social education adaptability. The researchers stressed that it is absolutely good to eat more fish. Therefore, as long as you pay attention to fish health and standard heavy metal content, parents should encourage pregnant women and children to eat more fish, and children will be smarter.

● Environmental scientists also pointed out in particular that heavy metal pollution is not the only problem for fish. Chemical substances produced by industrial wastewater, garbage, and other pollutants are deposited in the fish, causing consumers to have nervous and immune system lesions. Such fish The problem of pollution is more worthy of attention. Therefore, when buying fish, it is best to buy live fish, followed by the place of origin, and there are fewer pollutants in the fish far from the industrial area.

Note: Pregnant women often eat mercury fish easily miscarriage

Pregnant women who eat tuna (carp) must be careful! American environmental groups have found that the content of mercury in seven types of seafood, including tuna, is exceeding the standard, and regular consumption of pregnant women will cause birth defects. The group suggested that the U.S. Food and Drug Administration should expand the blacklist of “silver fish”. A Hong Kong doctor pointed out that the excessive absorption of mercury from the fetus in the mother’s body can affect the development of nerves in the brain, the ability to learn in the future will be flawed, and mental development will be delayed. And other sequelae.

Pregnant women should eat less canned fish

In January of this year, the U.S. Food and Drug Administration announced that the levels of mercury in four species of fish (sharks, mackerel, swordfish, and magas) were too high to be consumed by pregnant women, pregnant women planning to be pregnant, feeding mothers and children.

The latest report on the level of mercury in seafood issued by the U.S. Environmental Working Group and the Public Interest Research Group indicated that 7 types of seafood must be added to the black list to protect women and children from mercury poisoning. The seven types of seafood are tuna, oysters from the Gulf of Mexico, sea bream, white catfish, marlin, pike and white mouth.

The report also recommended that pregnant women should reduce the consumption of canned tuna, spearfish, squid and pollock, because the canned fish is also very high in mercury, and the amount of food should be limited to once a month.

The U.S. Environmental Working Group pointed out that seafood that can be safely consumed by pregnant women includes artificially reared eel and salmon, shrimp, left-mouth, Pacific salmon, yellow croaker, mid-Atlantic blue crab, and black-and-white crab fish.

Destruction of the central nervous system

In the United States, there are as many as 60,000 newborn babies each year. Inhalation of excess mercury in the mother's body disrupts the central nervous system and affects the cognitive function in the future. Li Jiaren, a pediatrician in Hong Kong, pointed out that pregnant women's inhalation of excess mercury has a far greater impact on the fetus than on the mother. He pointed out that in Japan in the 1960s, a river in a village was contaminated by mercury discharged from an upstream factory. Pregnant women in the village subsequently gave birth to babies with malformed brains. After a survey conducted by local governments, they finally discovered that they were pregnant women. Drinking water with high levels of mercury into trouble.
